Five items among neurobehavioral core test battery of World Health Organization, including Santa Ana dexterity, pursuit aiming, digit symbol, simple reaction time, and Benton visual retention, were administered to the workers occupationally non-exposed to neurotoxic agents by operational guide for the WHO neurobehavioral core test battery. Subjects were volunteers from the industrial workers(117) and clerks(40). Detailed occupational history such as exposed agents including noise or vibration, educational level, residence, smoking and drinking habit were recorded. Most of the neurobehavioral tests were correlated with age and educational level. Smoking was correlated with pursuit aiming and digit symbol. Vibration affected pursuit aiming. Job type(industrial workers vs. clerks) and noise exposure did not affected among tested items. Multiple regression analysis was done for establishing predict equation to estimate normal ranges of the tests for male workers. Age was shown to be main independent variable affected for all tests except wrong dot of pursuit aiming. Educational level was also shown to affected most of the tests except Santa ana dexterity and wrong dot of pursuit aiming. Alcohol consumption affected Santa Ana dexterity, non-preferred hand, and smoking affected only wrong dot of pursuit aiming after multiple regression analysis.

Occupational hearing loss became the leading occupational disease by constioution 56% of all work-related diseases in Korea. However, the prevalance rates showed wide variations among the specific medical examination providers and were very low(0.8-1.4%) compared with those 8.4% in Japan. The sources of these variations was regarded in the preview study as 1) Employee audometric estings were primarily conducted by nurses and nurse-aids who had no formal training for audiometry; 2) althought audiometric testing equipment used by the spedific medical examination providers, it should be periodically calibrated, a significant number of them were not properly calibrated : 3) Initial audiometric testings were conducted at any available spaces in workplace or at the testing room without considering bachground noise level. One of solutions that can be done for sloving surrent noise related problems is to provide a noise related manual for the occupational health managers including doctors, nurses and hyginests. This study was done to provide such a manual. The main core of the manual was hearing conservation program. And the contents of the manual was the same as the main frame of hearing conservation program such as noise survey, provided of the diagram showing the core contents of each factor of the hearing conservation program. Hopefully, this manual will be the references of the standardized performances of the specific medical examination providers.

Purpose; Ga-67 scintigraphy has been used for the evaluation of tumors, especially lymphoma. Recently, Tl-201 and Tc-99m MIBI were also used to tumor imaging. Tl-201 and Tc-99m MIBI had better physiologic characteristics than Ga-67, so we studied 32 biopsy proven lymphoma patients (male 24, female 8, mean age 46 years) with Ga-67, Tl-201 or Tc-99m MIBI and compared the scan findings. Materials and Methods: Twenty-three of 32 patients were injected 74-111 MBq (2-3 mCi) of Tl-201, before chemotherapy and imaged with dual-headed SPECT (Prism 2000, Picker, USA) at 30 minutes after injection. Delayed images were obtained after 3 hr in 8 patients. Twenty seven of 32 patients were injected 740 MBq (20 mCi) of Tc-99m MIBI and imaged at 30 minutes after injection. 111-185 MBq (3-5 mCi) of Ga-67 was injected in 12 patients and imaged at 48 and 72 hours after injection. Twenty eight patients were diagnosed as non-Hodgkin's lymphoma and others were Hodgkin's lymphoma. Results: Twenty patients were positive on Tl-201 scan and 3 patients showed negative findings. One of these 3 patients, Tc-99m MIBI and Ga-67 scan were positive. Twenty two patients were positive on Tc-99m MIBI scan and 5 patients showed negative findings. One of these 5 patients, Tl-201 was positive and 2 were positive on Ga-67 scan. Ten of 12 patients showed positive findings on Ga-67 scan. The sensitivity of these agents were 83.3%, 87.0% and 81.5% for Ga-67, Tl-201 and Tc-99m MIBI, respectively. The sensitivity was highest in Tl-201 scan, but there were no significant differences among three tests. In this study, there was no significant difference of uptake ratios between early and delayed images of Tl-201. Conclusion: Scintigraphy with Tl-201 and Tc-99m MIBI in lymphoma patients have similar sensitivity with Ga-67.

연구목적은 동작관찰훈련이 뇌졸중 환자의 인지기능 향상에 영향을 미치는가를 알아보고자 하였다. 연구방법으로는 2018년 4월 23일부터 5월 18일까지 경인지역 병원에 입원 중인 재활환자 7명을 대상으로 MMSE-K와 LICA를 사용하여 평가를 진행하였고, 동작관찰프로그램으로는 상지 ROM 댄스, 풀 오버형 옷정리, 운동화 끈 묶기, 수건 개기, 양말 개기, 종이접기, 넥타이 매는 법 총 7가지 과제를 적용하였다. 통계프로그램으로는 SPSS version 20을 사용하였으며 기술통계, Wilcoxon signed ranks을 사용하여 값을 구하였다. 동작관찰훈련을 적용한 결과 MMSE-K 점수는 3.29±1.38의 변화량을 보여 p값 0.001로 유의한 값을 보였고, LICA 점수는 기억력에서 12.16±6.73으로 가장 유의한 값이 나왔다. 결론은 동작관찰훈련이 뇌졸중 환자의 인지기능 영역 중 기억력에서 가장 많은 영향을 미쳤으며, 다른 영역에서도 점수 향상은 있었으나 통계적으로 유의하지는 않았다. 앞으로 동작관찰훈련이 많이 사용되어 추후에는 뇌손상 부위별로 어느 영역에서 효과가 있는지에 대한 후속 연구가 이루어지길 바란다. This study aims to identify whether the action-observation training impacts on the improvement of stroke patient’s cognitive functioning. When it comes to the research methods, Korean version of Mini-Mental State Examination (MMSE-K) and Literacy Independent Cognitive Assessment (LICA) conducted to assess samples between 23 April and 18 May 2018. Samples are seven patients who are hospitalized in Kyung-In region. In the meantime, seven tasks such as the range of joint motion (ROM) dance, arrangement of pullover clothes, lacing-ups of a pair, folding up a facecloth and socks, the origami and tying a necktie implemented as the action-observation programme. In order to analyse collected data, descriptive statistics analysis, paired t-test and the Wilcoxon signed-rank test were carried out via SPSS version 20 (a statistics programme). The change in value from MMSE-K showed its statistical significant as 3.29 (±1.38, p<.001) as well as value from LICA in recollective powers was 12.16 (±6.73), therefore, the statistic is said to be statistically significant. In conclusion, action-observation training most influenced recollective powers amongst stroke patient’s cognitive functioning areas. Even though development of cognitive functioning discovered in other areas, its values were possibly statistically insignificant. Hence, future research ought to demonstrate which areas action-observation training is effective according to brain lesion site.

Purpose: Death is not an option but a necessity in our life. However, there is little understanding of what a good death means. This study was conducted to analyze the concept of a good death by exploring attributes, antecedents, consequences and empirical criteria for a good death in literatures. Method : Reviewed materials were collected by searching for web cites such as PubMed, National Library of Korea, National Assembly Library. Walker and Avant's method(2004) was used for this concept analysis. Results : The findings showed that a good death includes seven attributes: dignity (personal respect and privacy), self-control (the right of choice, independence, clear consciousness), comfort (physical, psychological, spiritual). optimal relationships (supportive environment, proper care, restoration of relationships), appropriateness (sequence and proper age of death), preparation for death (completing unsettled tasks, leaving a legacy, positive attitude toward life, awareness and acceptance of death) and minimizing burden. Conclusion : This results will provide health professionals and people with a preliminary understandings of a good death. In addition, there is the need for further study to develop objective measurement of a good death and effective nursing intervention for the dying.

This study was carried out in order to investigate dextran formation and internal structure during fermentation of the oligosaccharide Jeung-Pyun. The dextran and sugar reducing contents of Jeung-Pyun batter and the specific volume and the internal structure of Jeung-Pyun were analyzed as a function of fermentation time. The specific volume of Jeung-Pyun peaked at the 7th hour of fermentation. The dextran content of Jeung-Pyun batters peaked at the 7~13th hour of fermentation, and Fructooligosaccharide Jeung-Pyun had the least peak value. Reducing sugar content of Jeung-Pyun batters slowly decreased as fermentation progressed. From the air pore size and distribution of Jeung-Pyun observed by SEM, the sucrose Jeung-Pyun fermented for 3~7 hours and oligosaccharide one fermented for 7 hours were judged as the best. It was concluded that dextran may be formed by fermentation of oligosaccharides as well as sucrose and dextran has a significant role on the volume expansion of Jeung-Pyun.
